aoormo MATERIQL.

To all whom it may concern:

Be it known that I SrLAs M. FORD, a citizen of the United tates, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Roofing Materials, of which the following is a specification..

This invention relates primarily to shingle strips formed of water-proofed paper, felt, or material of a similar nature, which may or may not be covered with a mineral surfacing.

One object of my invention is to provide in a shingle strip an improved reinforcement of such nature that the shingle strip placed next above will butt against the top ends of the reinforcement.

Another object is to provide an inexpensive-form of shingle strip that will simulate the appearance of individual shingles.

This invention relates secondarily to forming on sheets of roofing material various designs of such'nature that when the sheets of roofing are laid on the roof the roof will appear to be covered with shingles.

With these-and incidental objects in view, the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms a part of this specification.

In the drawing, Figure 1 is a fragmentary plan view of a strip of suitable material and dimensions for making thereof a shingle Fig. 2 is a similar view, but showing where the mineral surfacing has been scraped away to prepare a strip for the application thereon of reinforcing strips; 3 is a similar view of a completed shing e strip; Fig. 4 is a section taken on the line 4-4, Fig. 3; Fig. 5 is a section taken on the line 5--5, Fig. 3; and Fig. 6 is a plan view of a fragment of a roof, showing my improved shingle strips applied thereon; Fig. 7 is a plan view of a fragment of a sheet of roofing showing one form of shingle design thereon; Fig. 8 is a similar view but showing a different design; 'and Fig. 9 is a simi* lar view but showing a third design.

A strip of suitable material of proper dimensions, such as 1, Fig. 1, may have the mineral surfacing scraped away, as at 2, Fig. 2, so as to expose the weather-proof coating, which is of a more or less tacky Specification of Letters Patent.

nature so that reinforcing strips 3, Fig. 3, which have their under side covered with a tacky substance, when pressed firmly onto the strip 1, Fig. 2, at points 2, will tightly adhere thereto, the tacky substances of the,

strip and reinforcing strips blending or uniting so the reinforcing strips will be permanently-joined to the shingle strip.

When the shingle strip has been thus pre pared with the reinforcing strips, tabs 4 are formed between the reinforcing strips 3, simulating to an observer at a comparatively short distance the appearance of unit shingles, and when a plurality of such shingle strips are superimposed, one upon the other, on a roof in shingle fashion as shown in Fig. 6, the appearance is pleasing to the eye, and gives a heavier appearance to the shingle strips than would be the case were the spaces 2 cut away from the strips.

It will be readily seen that in a stri with the spaces 2 cut out the protection a ordecl against water blowing up under'the shingle strip is comparatively small.

For instance, in a shingle strip where the exposed shingleis to be four inches, such a strip would ordinarily be ten inches wide; when one strip is placed upon the other in shingle fashion the distance from the top of the cut away gutter of the top strip to the upper edge of the strip next underneath would be only two inches, so that the protection against rain beating up under the top strip would be slight.

With my improved shingle strip, however, if the exposed portion is to be four inches, the strip need only be eight inches wide to make a protection of four inches against water blowing up between the Patented Jan. 18, 1921..

shingle strips, as there is no cut away portion.

In addition to this the mere fact that none of the shingle strip is cut away greatly strengthens the strip itself, and in addition to that, the placing of the reinforcing strips entire surface coated with a. mineral surfacing and the reinforcing strips 3 placed thereon in the same manner shown in Fig. 3, these strips having a sufficient amount of tacky substance on the bottom thereof to firmly unite with the water-proofcompound below.

Likewise that portion of thestrip above ends 5 ofthe shingle strip may be left free of mineral surfacing so the next strip above will mat down firmly and unite with the lower shingle strip.

It is, of course, evident that the strips 3Lmay have a mineral coating of the same color as that of the strip to which they are applied, or may have a different color so they will stand out more strongly against the background, or that they may bev left free ofmineral surfacing so as to present the appearance of a heavy black space.

As shown in Fig. 7 the sheet of roofing material has reinforcing strips 7' positioned transversely on the face thereof, and reinforcing strips 8 positioned longitudinally thereof in such manner that a shingle outline is presented to the observer.

It will be noted that the strips 8 do not quite fill the spaces between the strips 7, leaving water openings 9 therebetween, so the water will not block up behind these strips.

In the style shown in' Fig. 8 the design is completed by the strips 7, the strips 8 being entirelv omitted.

In the design shown in Fig. 9, a diamond shaped outline is built up of strips 10 and 11, a Water space 12 being left open in the lower end of each diamond, so as to allow water to run free therefromi As in the ease of shingle strips, the reinforcing strips which form the outline of the designs serve to reinforce the strips so that when placed upon the roof they will be held flat and rigid instead of wrinkling up as ordinary roofing sometimes does.

\Vhile I have described my invention and illustrated it in several particular designs, I do not wish it understood that I limit myself to this construction, as it is evident that the application of the invention may i be variedin many ways within the scope of the following claims.

Claims:

1. Roofing material composed of a strip of suitable material and having reinforcing strips positioned transversely thereof and extending from one edge thereof to reinforce said strip and to simulate the appearance of individual shingles.

2. Roofing material composed of a strip of suitable material having no portions thereof cut away. and having reinforcing strips applied to the surface thereof and extending part way transversch across said strip, from oneedge thereof.

3. Roofing material comprising in combination av strip of suitable material and a plurality of reinforcing strips of roofing material positioned transversely of said first named strip and extending from one edge thereof, partially across one surface of said strip, said reinforcing strip being united to said first named strip by a. tacky substance.

4. Roofing material comprising in combination a strip of suitable material having a mineral surfacing on one side thereof, and having narrow, evenly spaced portions thereof free of said mineral surfacing, and reinforcing strips superimposed on said portions, and matted thereto to reinforce said roofing material and simulate the appearance of unit shingles.

5. Roofing material comprising in combination a sheet of fibrous material and a plurality of reinforcing strips superimposed on the face of said fibrous material and arranged in designs to simulate the appearance of unit shingles.
